Class VariableGapTermsIndexWriter

Selects index terms according to provided pluggable VariableGapTermsIndexWriter.IndexTermSelector, and stores them in a prefix trie that's loaded entirely in RAM stored as an Lucene.Net.Util.Fst.FST`1. This terms index only supports unsigned byte term sort order (unicode codepoint order when the bytes are UTF8).

Note

This API is experimental and might change in incompatible ways in the next release.
